摘要： A management apparatus reduces the number of pieces of unique information each not generated from another piece of unique information, among unique information being bases of keys assigned to managed apparatuses.The management apparatus calculates, for nodes in layers other than tree structure leaves, subsets of apparatus identifiers subordinate to the nodes, searches for a subset wholly containing another subset in the lowermost layer other than a leaf layer from an immediately-upper layer and mutually associates these subsets, searches for another subset wholly containing the containing subset from a same or an immediately-upper layer and mutually associates these subsets, controls this processing to repeat up to the uppermost layer, controls these processings to repeat on all subsets in the lowermost layer, makes unique information correspond to subsets in the lowermost layer, and makes information derivatively obtained from the unique information correspond to subsets connected due to the associating.

摘要： Provided is a two-dimensional code structured in such a way that the identification function for each of multiple components constituting the two-dimensional code, which have been concatenated and encoded in the form of structured append, has been enhanced. In a set of multiple two-dimensional codes that have been encoded in the form of structured append, wherein the two-dimensional code comprises an information area, an illustration area, and a parity area, each two-dimensional code which is a component of the set of multiple two-dimensional codes is a two-dimensional code having the same graphical illustration drawn in the illustration area.
